Temperature Sensors - PTC Thermistors – B59008C180A40 application field and working principle

Temperature sensors are used to monitor temperatures in a wide variety of applications. They are widely used in consumer electronics, medical devices, chemical and pharmaceutical industry, and manufacturing. One of the most commonly used temperature sensors is a PTC thermistor.

PTC thermistors (positive temperature coefficient) are solid-state semiconductor devices based on semiconductor materials with changeable electrical resistance, determined by their temperature. This property of the material is called the “positive temperature coefficient” (PTC). The B59008C180A40 is a particular example of one commonly used type of PTC thermistor.

The B59008C180A40 is mainly used in the temperature sensing, temperature compensation, overload protection, and thermal relay applications. It works by sensing the temperature and providing a voltage output signal. When the external temperature rises, the resistance of the PTC thermistor increases too, generating the output signal voltage. For this particular model, its resistance falls in the range of 5.9 Ω~ 27 Ω at 25 °C. Its resistance coefficient is 10 ~ 40 times larger than a NTC thermistor.

When the B59008C180A40 is used in a circuit, a pre-set voltage is applied to the sensing terminal of the PTC thermistor, and its load will vary acording to its temperature changes, which will generate a voltage proportional to the temperature. This voltage feedback will be processed by the signal receiving module. By processing the voltage feedback, temperature control, overload protection, and temperature compensation can be performed.

The B59008C180A40 has a wide application range. It can be used to help protect against overload and temperature rise in electrical circuits. Owing to its features, such as small size, high accuracy, high sensitivity, low cost, and fast response, the B59008C180A40 is widely used as a temperature sensor in various industrial and consumer electronic applications.

In conclusion, PTC thermistors are widely used as temperature sensors in a variety of applications. The B59008C180A40 is one specific example of PTC thermistors and can be used for overload protection and temperature compensation, due to its features, such as small size, low cost, high accuracy, and fast response.
